<p>A method of dredging a pond uses a submersible assembly, having a dredging cutter and submersible pump, which is submersed in the pond. The submersible assembly is moved along a bottom of the pond by winches. A controller receives signals from a global positioning system as to the position of the submersible assembly in the pond and moves the submersible assembly in a continuous dredging pattern through the coordinated operation of the winches.</p> |
